tough to take a break , what to do?

It takes around 20-30min to open 6 good tables if its prime time 10-12pm(europe) and 1hour+++ other times of the day , the problem is that its so hard to find those tables that you have to commit and play a big session with no breaks 4+hours, i used to play zoom where taking a break and opening a table was so easy but regular cash is tough in this manner.

Any advice how to endure 4+ hours session? how can you occupy yourself and take some stress away?
